Hi Maria,
The pertinent part is pasted here:
Growing medium
? Use quality substrates with pre-determined analysis for hygiene reasons
? Loam potting growing medium can be used, has to be sterilized by steam.
Soil analysis before use.
? Components: 15-25% clay is of advantage:
better buffer
better leaf wetness
stable pH
result: more compact and hardy plants
? pH: Peat substrate 5.6 - 6.0
Clay-peat-substrate 5.8 - 6.2
Check pH during the cultivation, as it can vary depending on substrate and
hardness of water.
But, it does not say what kind of clay. That is the part I am still looking
for. Will keep you posted if I find anything. I am finding more sources
for those high fired clay pellets, though. Home Harvest has another brand.

Sandy if you could just tell me what form of clay (baked pellets?) Fides
Plants recommends I'd appreciate it. My Mac doesn't speak .doc. I've
already repotted about a dozen seedlings with clay pellets added and I
notice they're not drying out so soon.
